The wireless soil moisture sensor PASCO sensor PS-3228 can be used for environmental science, agricultural science, horticulture and biology experiments.
This product can connect directly to a computer or device using Bluetooth wireless technology.
The wireless soil moisture sensor determines the percentage of water content by volume of soil (% VWC) by measuring the dielectric constant of the space surrounding the blade-shaped capacitor. The electric field generated by the sensor responds to the capacity of the surrounding space and calculates the percentage of soil water content by volume.
Liquid water has a uniquely high capacity, making it a major contributor to sensor measurement. The sensor is factory calibrated for soils with a discrete water content by volume and output readings as a percentage of the filled room. Accurate readings range from 0%, with little or no moisture in the dried sample, to 45%, where the entire pore space inside the soil is saturated with water. To read% Saturation, divide the value by 45.
The sensor is calibrated to support analyzes on three predominant soil types: sandy soil, clay soil and clay soil. If you are unsure of your soil type, choose intermediate calibration, clay soil that fits the widest range of conditions.
How to use PS-3228?
This product requires PASCO software to collect and analyze data. We recommend the following options: SPARKvue or Capstone.
To use the sensor, dig a hole 5 cm above the ground and place your spear-shaped part of the sensor in the soil. For best accuracy, be sure to wrap the soil tightly around the sensor. After use, the surrounding soil must be loosened to reduce the risk of damaging the sensor cable.
